PURPOSE:To accurately grasp the positional relationship between a magnetic sensor and a living body to measure the magnetism of the living body. CONSTITUTION:A frame having indexes removably mounted thereto to indicate characteristic points of a living body to be measured and capable of being photographed is attached to the living body. A transmitter and receiver respectively for transmitting and receiving the three-dimensional magnetic field of a three-dimensional coordinate input device are mounted on the frame and a magnetic sensor respectively to measure the magnetism of the living body while the positional relationship between the frame and magnetic sensor is grasped. From the index image in a picture having the living body photographed while the three-dimensional coordinate input device is removed, the positional relationship between the living body and magnetic sensor in measuring the magnetism is obtained. |
